Despite normal peripheral sensitivity, the possibility remains that tinnitus may be associated with deficits to which conventional audiometry is not sensitive (Liberman et al., 2016). This study investigated the utility of extended high-frequency (EHF) threshold testing, distortion product otoacoustic emissions (DPOAEs), and contralateral suppression of DPOAEs as potential indicators of tinnitus in normal hearing. Results indicate that these measures, particularly DPOAEs, may reflect cochlear damage related to tinnitus that is not reflected in conventional audiometry.
